UNITED STATES PATENT OFFICE.

WILLIAM WATSON GRIER, OF GOSI-IEN, INDIANA.

PRINTING-CYLINDER.

SPECIFICATION formingpart of Letters Patent No. 711,495, dated October21, 1902. Application filed February 4,1901. serial No. 45,839. (Nomodel") T0 at whom it may concern.-

Be it known that I, WILLIAM WATSON GRIER, of Goshen, in the county ofElkhart and State of Indiana, have invented a new and usefulPrinting-Cylinder, of which the following is a full, clear, and exactdescription,reference being had to the accompanying drawings, formingpart of this specification, in Which Figure 1 is a longitudinal sectionof a cylinder, showing the method of building up the same according tomyinvention. Fig. 2 is a broken cross-section, on a larger scale, of acylinder with the type-strips thereon. Fig. 3 is a partial sideelevation of the cylinder with aportion of the type-strips appliedthereto. Figs. 4 and 5 are detail cross-sections showing differentarrangements of the strips, and Figs. 6 and? are broken detail views ofanother form of type-strip.

My invention relates to the printing of graining designsupon Woodenpanels to imirate the natural grain ofwoods, such as quartered oak, andis designed to provide an improved cylinder therefor which can becheaply and simply made and will give continued service without injurythereto.

Inthe drawings, 2 represents the body of the printing-cylinder, havingend flanges 3 3 and supporting-trunnions 4 4.

The types for printing the design are formed from a strip or stripswhich are wound around the cylinder in planes substantially at rightangles to the cylinder-axis, the edges of the strips forming the type.In order to give the desired design, I preferably cut the type-stripinto separated type, each connected to a common base-strip in thefollowing manner: The strip is first punched to form transverse slots5,and then diagonal cuts are made extending from the top edge of thestrip into these slots or holes. The diagonal cut leaves the type withsharp edges, having acute angles at one side thereof, these types allbeing held together by the strip extending along the base portion of theslots. The upper edge portions of the strip are then hammered or rolledupon the sides, so as to reduce the thickness of the strips and give theproper opening between the adjacent type. This operation at the sametime elongates and sharpens the printing edge of the type and givesacurve to the ribbon or strip, so that it will fit the curve of thecylinder. A strip formed into type in this manner is wound around thecylinder-body at one end, and the adjacent layers are then forcedtogether in any desired manner and secured in place. I preferably windthe strip or ribbon upon the cylinder under a considerable ten-- sion,so that it fits to the cylinder tightly, and to pack the type together Ipreferably employ bars 6, whose ends are placed against a strip, theother ends then being acted upon by screws 7, extending through theopposite flange of the cylinder. When a ribbon has thus been pressed toplace, I preferably secure it by drilling small holes through thecylinder and driving steel plugs 8 into these holes, as shown in Figs. 2and 3. To vary the type from extending in straight lines around thecylinder in addition to the curves naturally produced by pressure of thepins 8, I insert between the successive layers of the strip short'piecesof the strip having varying lengths. These shortpieces form curves inthe main type-strip and also aid in putting heavy tension upon the bandsof type, so as to press them rigidly to the cylinder. In Fig. 3, I showa curved part of the ribbon thus formed. These short lengths may bedriven in wherever desired and according to the design of graining whichis wanted. A pleasing variation can thus be introduced by the insertionof the short lengths, by the pressure of the pins, or by other suitablemeans. Successive lengthsrof the type-ribbons are thus 'wound andsecured, and the holding-pins may be removed successively as theadjacent strips are secured. The cylinder may thus be filled its entirelength with the type-bars or for a portion only of its length ifnarrower panels are to be printed. After the cylinder is thus comquentlyproject above them and need not be reduced in thickness. In this formthe strip 10 would also be substantially continuous, being wound inspiral form in the same manner as the main strip. The supplemental stripmay be composed of thin veneer-paper or other suitable material. Thetype strip or ribbon may be formed as shown in Figs. 6 and 7. In thisform a straight steel ribbon is compressed, with tapering recesses 11 onone or both sides, by passing it under a hammer or press. This actionforms the desired curve in the strip and at the same time makesdivisions resembling type.

This cylinder may be used in the same manner as ordinaryprinting-cylinders, the type being inked and the panel being passedunder it, so as to print the .graining design thereon.

The advantages of my invention will be apparent to those skilled in theart, since a printing-cylinder may thus be obtained which is not liableto get out of order and can be made at comparatively small expense,while beautiful effects in graininglines may be obtained.

Many variations may be made in the shape and size of the type ribbons orstrips, as well as in the formation of the type, without departing frommy invention.

I claim 1. A printing-cylinder having a printingribbon wound edgewise inspiral form thereon; substantially as described.

2. A printing-cylinder having a series of ribbons wound thereon inspiral form,the edge portions of the ribbons being formed into type;substantially as described.

A printing-cylinder having a metallic ribbon wound thereon in spiralform, the edge portions being severed into separated type by a diagonalcut; substantially as described.

at. A printing-cylinder having a metallic ribbon Wound thereon, saidribbon having holes or slots in its body and cuts extending into thesaid slots forming type; substantially as described.

5. A printing cylinder having metallic strips wound thereon in spiralform, said strips being bent into a curve at various points;substantially as described.

6. A printing-cylinder having strips of metallic ribbon wound edgewisethereon in spiral form and held under endwise compression, said stripshaving separated type portions at their outer edges; substantially asdescribed.

7. A type-cylinder having lengths of steel ribbon wound thereon and heldunder endwise pressure by pins extending into the cylinder, said stripshaving edge portions forming type; substantially. as described.

8. A type-cylinder having a ribbon wound edgewise thereon in spiralform, the adjacent layers of the ribbon being separated byspacing-strips of less height; substantially as described.

9. A printing-cylinder having a metallic ribbon wound edgewise thereon,said ribbon having tapering indentations pressed therein; substantiallyas described.

In testimony whereof I have hereunto set my hand. 7
